Hi Admin,

Thanks for the insights.

It's working as expected.

Will explore more on it and let you know any issue we face in future.

Hi Admin,

Thanks for your reply.
I followed the same. templates with helpers, content, engine, recipe, chrome are fine. For my template i need to pass the set of data as Json , How can i send the data to that function .
below is the code implementation

const requestBody=event.renderRequest
const resp = await jsreport.render(requestBody);

in requestBody will contain below data

{
template: {
content: "Hey Buddy this is called from the backend you know",
engine: "handlebars",
recipe: "chrome-pdf",
chrome: {
format: "A4",
orientation: "portrait",
fittopage: true,
margin: {
top: "30px",
left: "20px",
right: "20px",
bottom: "10px",
},
},
helpers: "function myFunction (x){return x}",
}
datas:[{temp1:"temp1Data"},{temp2:"temp2Data"}]}
}

Because these datas needs to be bind with my template.

Kindly check above and guide me to close this .

Thanks.

I configured this in Lambda function and i got the Functional URL aswell.
I need to use this service by calling this form Node Project.

Consider i have my templates and data and rest of the parameters.

How can i call this In my nodeJs and being served by lambda.

Hi Team, Good day.

In this Post i want to clarify that Can i send the data like given below to the jsreport starter kit which is used for lambda based configurations REFERENCE LINK: https://jsreport.net/learn/aws-lambda-serverless

Sample JSON request:

{
    "renderRequest": {
        "template": {
            "content":`
\n' +
'<html lang="en">\n' +
'\n' +
'<head>\n' +
'  <meta charset="UTF-8">\n' +
'  <meta name="viewport" content="width=device-width, initial-scale=1.0">\n' +
'  <title>My Website</title>\n' +
'\n' +
'</head>\n' +
'\n' +
'<body>\n' +
'\n' + // Added an empty line before your content area

'  <header>\n' +
'    <h1>Welcome to My Website</h1>\n' +
'  </header>\n' +
'\n' +

'  <main>\n' +
'    <h2>Example Table</h2>\n' +
'    <table>\n' +
'      <tr>\n' +
'        <th>Name</th>\n' +
'        <th>Age</th>\n' +
'        <th>City</th>\n' +
'      </tr>\n' +
'      <tr>\n' +
'        <td>John Doe</td>\n' +
'        <td>30</td>\n' +
'        <td>New York</td>\n' +
'      </tr>\n' +
'      <tr>\n' +
'        <td>Jane Smith</td>\n' +
'        <td>25</td>\n' +
'        <td>London</td>\n' +
'      </tr>\n' +
'    </table>\n' +
'  </main>\n' +
'\n' +

'  <footer>\n' +
'    <p>&copy; 2024 My Website</p>\n' +
'  </footer>\n' +
'\n' +  
'</body>\n' +
'\n' +
'</html>\n'
`
`;

                }
            },
            "helpers": " function myFunction (x){return x}"
        }
    }
}

In lambda actual jsreport npm packages not working. So i tried this way to implement the actual jsreport functionality in lambda based.

I will send the Request like given above. Kindly confirm whether this is right approach or not. Kindly guide me to get this done.

Thanks in advance

Hi Admin, Greetings of the day.

I have found my lambda function and got the code and i debugged the place and finally i found the place where that actual error is occur.

Code given below for more clarity:

In above code i have highlighted the part where that error occour.
Why that path2.dirname(require.main.filename) la filename property is undefined.

Help to get the root cause for this. Im not sure is this directory permission on AWS lambda. If anything like directory changes kindly let me know i will update my User permissions acccordingly.

Waiting for your message .

Folks If you have any insights please feel free to share. Thanks in Advance

In the given Tutorials Those are all manually create function and Layer building. But In our app is Doing everything all by automatic . We have serverless.yaml file to configure those things.

My Doubt is Why we need to clone that Repo first , How do that code will impact with my my Node Application.

Help me to get clear picture on this please. Let me know if you need any additional information.

jayakumar1998

Hi Admin, Thanks for your response.
As you instructed i have added the rootDirectory: __dirname in my jsreport-core and details given below. Still same issue exist , After deployment on lambda My Node App crash and Not running . throws 500 Error for all API calling. I![alt text](image url) have attached my configurations and Kindly check that and let me know what i missed.

import * as _ from "lodash";
const jsreport = require("jsreport-core")({
rootDirectory: __dirname,
});
jsreport.use(require("jsreport-handlebars")());
jsreport.use(require("jsreport-chrome-pdf")());
jsreport.use(require("jsreport-html-to-xlsx")());
jsreport.use(
require("jsreport-assets")({
searchOnDiskIfNotFoundInStore: true,
allowedFiles: "/.",
})
);
jsreport.init();

Kindly help me on this. I have added the Jsreport dependency in my layers package.json file also.
